Member

ulSize

Type: UINT32

The size (sizeof(stcStorageSettings)) of the structure.

guidId

Type: GUID

The globally unique ID of the domain.

strName

Type: wchar_t*

The name of the domain. This name is only used in GUIs.

ulFlags

Type: UINT32

0x1 Enabled (read-only, use “EnableStorage” to set it).

usStorageId

Type: UINT16

The ID of the storage in relation to the domain.

ubtServerId

Type: UINT8

The ID of the server in relation to the storage.

ubtSecureBlockShift

Type: UINT8

Defines the size of a block that is written in a single operation (atomic) by the storage device used. The size of a block is 1 << ubtSecureBlockShift. If the value is less than 9, the value is increased so that a minimum block size of 512 is created.

ulLogDataPoolLength

Type: UINT32

The log blocks’ count for incoming write requests is kept loaded in the memory.

ulLogDataReplicationPoolLength

Type: UINT32

Always 0.

ulLogDataBlockSize

Type: UINT32

Size of log blocks.
Minimum value: 1048576 (1 MB)
Default value: 1048576 (1 MB)

ulMinStorageElementCount

Type: UINT32

Minimum count of objects that can be stored inside an object storage.
Minimum value: 32
Default value: 32

ulMaxStorageElementCount

Type: UINT32

Maximum count of objects that can be stored inside an object storage.
Minimum value: 8192
Default value: 8192

ulMinStorageDataSize

Type: UINT32

Minimum size of object data that can be stored inside an object storage.
Minimum value: 4096 (4 KB)
Default value: 4096 (4 KB)

ulMaxStorageDataSize

Type: UINT32

Maximum size of object data that can be stored inside an object storage.
Minimum value: 8388608 (8 MB)
Default value: 8388608 (8 MB)

ulDeltaStorageDataSize

Type: UINT32

Size that the object data size is increased or decreased by when more or less space is needed.
Minimum value: 131072 (128 KB)
Default value: 131072 (128 KB)

ulMinPartObjectCount

Type: UINT32

Minimum count of objects inside a part of the caching table for open objects.

ulMaxPartObjectCount

Type: UINT32

Maximum count of objects inside a part of the caching table for open objects.
Minimum value: 64
Default value: 64

ulCacheHalfLife

Type: UINT32

Time in milliseconds after which the system tries to reduce the size of the data inside the cache if the data has not been used.

ulMinStorageCount

Type: UINT32

Minimum count of object storages kept loaded in the memory for caching.

ulMaxStorageCount

Type: UINT32

Maximum count of object storages kept loaded in the memory for caching.

ulDeltaStorageCount

Type: UINT32

Delta count that the storage count is reduced by after not being used for more than the ulCacheHalfLife time.

ulMinPartCount

Type: UINT32

Minimum count of caching tables for caching objects.

ulMaxPartCount

Type: UINT32

Maximum count of caching tables for caching objects.

ulDeltaPartCount

Type: UINT32

Delta count that the part count is reduced by after not being used for more than the ulCacheHalfLife time.

ulWriteDownThreadCount

Type: UINT32

Count of threads to be used to make logged transaction changes to the data in the database.

ulMaxIncompleteTransaction

Type: UINT32

Maximum number of incomplete transactions. A transaction is complete once it is fully processed. This is when it has been logged and all the changes have been made to the data in the database.
The system delays the execution of client write requests until the count of incomplete transactions falls below this limit.

ulReplicationThreadCount

Type: UINT32

Always 0.

ulEventThreadCount

Type: UINT32

Count of threads to be used for event handling. Events are sent to clients to inform them of changes to the database.
